Load Balancing Linux Router Setup

Hey all,

I'm looking to pump a little more bw out of my shared 22mbit line, my main box is running 2k pro as I require certain apps, but unfortunately, no matter how many nic's I throu in the 2k box, 2k pro just wasn't designed to load balance. What I'm trying to do is use one nic in the 2k box running by way of a switch to a NiC on a linux box. Then from the linux box have two other NiC's as uplinks to the 22mbit network that are loadbalanced and stilil be able to route traffic through the internal network to the 2k box. My theory is that the two load balanced NiC's with two ip's will pull give me a bit more pull over the 22mbit switched network. Also, the linux box would be a great place for me to run an ftp bounce into the 2k machine as the packet shaper on the network queues by port number, and I could run the bnc on a different port and avoid the ftp crunch in the shaper.

I've found some documentationo on setting up a linux router, and some on load balancing, but nothing really has the flavor of what I want to do. If anyone has any suggestion or links to good docs on this I'd appreciate it. It may be more work than its worth, but it would sure be entertaining to get it working, not to mention mire secure.

thx ppls,

Are you trying to combine two 10mbit ethernet connections to a single 22 mbit upstream connection? Or do you want your upstream provider to round-robin your incoming connections to your two NICs?

the latter...

I'm talking about an edu network, and while locally its 100mbit, our pipeline off campus is only 22mbit... I think that if I can get the two nic's to act like one (ie in frame sequence 1, 2, 3, 4 I send frame1 throu eth0, 2 though eth1, 3 throu eth0...) then I double my slots in the nearest switch, hich while it won't double my bandwidth should offer some increase. I've definately heard of this, but I"m not sure how to do it
